Description

Technical Field

[0001] This utility model belongs to the field of sensor processing equipment, and in particular relates to a sensor packaging device. Background Technology

[0002] Sensor encapsulation is a commonly used sealing technology. It involves wrapping the sensor with an encapsulant such as epoxy resin, polyamide, or silicone, followed by curing. Encapsulated sensors offer excellent protection against mechanical shock and wear, as well as blocking dust and moisture, providing physical protection and environmental isolation, significantly increasing their lifespan. However, during the encapsulation process, the encapsulant material often contains numerous tiny air bubbles, mostly air introduced during material mixing. These bubbles are injected into the sensor's surroundings with the encapsulant and are difficult to remove. They typically affect subsequent sensor use, reducing the mechanical strength of the encapsulation, making it prone to cracking under impact, and compromising the seal. This exposes the sensor to moisture or chemical corrosion from the environment, further impacting its lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a sensor packaging device to solve the problem that during the sensor packaging process, there are often many small air bubbles in the sealing material. These air bubbles are mostly air mixed in during the material mixing stage. These small air bubbles are injected around the sensor with the sealing material and are difficult to remove. They usually affect the subsequent use of the sensor, reduce the mechanical strength of the sensor packaging, make it prone to cracking under impact, and damage the sealing of the sensor packaging. This allows the sensor to be exposed to moisture or other chemical corrosion in the environment, thus affecting the service life of the sensor.

[0004] To achieve the above objectives, the specific technical solution of the sensor packaging device of this utility model is as follows:

[0005] A sensor packaging device includes a base; a vibration chamber is disposed on the base; a motor is disposed inside the base; a rotating shaft extends from the output axis of the motor into the vibration chamber; a ball bearing is obliquely disposed on the outer side of the rotating shaft; a swing wheel is fixedly disposed on the outer side of the ball bearing; a swing fork is rotatably disposed on one side of the vibration chamber; the swing fork extends to both sides of the swing wheel and is rotatably connected to the swing wheel; an operating platform is fixedly disposed on the upper side of the vibration chamber; a slide groove is disposed on the operating platform; a slider is slidably disposed in the slide groove; a first clamping plate is fixedly disposed on one end of the operating platform at the slide groove; multiple springs are disposed between the side of the slider away from the first clamping plate and the operating platform; a second clamping plate is disposed on the upper side of the slider opposite to the first clamping plate; a support frame is disposed on one side of the base; an injection molding pipe is disposed downward on the upper side of the support frame and the operating platform; an injection molding nozzle is disposed between the injection molding pipe and the first and second clamping plates.

[0006] Furthermore, the operating platform is rotatably provided with an elliptical wheel at one end of the slide groove; an operating knob is provided extending from the elliptical wheel to the upper side of the operating platform; positioning grooves are provided at the four vertices of the elliptical wheel; and positioning posts are provided extending from the slider in the direction opposite to the positioning grooves.

[0007] Furthermore, buffer pads are provided between the four corners of the operating platform and the vibration chamber.

[0008] This invention provides a sensor encapsulation device with the following advantages: An operating platform is provided, on which the sensor to be encapsulated is placed. Sealant is injected into the sensor through an injection pipe and nozzle. The motor is then started, driving a rotating shaft. Simultaneously, the rotating shaft rotates the inner ring of a ball bearing. Because the ball bearing is tilted on the shaft, the rotation of the inner ring causes the outer ring to move up and down, simultaneously causing the oscillating wheel to swing up and down, generating vibration. The oscillating wheel's swing also causes the two sides of the oscillating fork to twist alternately up and down within the vibration chamber, increasing the vibration effect. The vibration force is transmitted to the sensor through the operating platform. This vibration accelerates the rise of air bubbles in the uncured sealant, causing tiny bubbles to coalesce into larger bubbles, making them easier to expel. Stable vibration also reduces the viscosity of the sealant material, aiding in bubble expulsion, increasing the sealant's density, and enhancing its protective effect on the sensor after curing. Pulling the second clamping plate causes the slider to slide within the groove, thus encapsulating the sensor. The sensor is placed between the first and second clamping plates on the upper side of the operating platform. Multiple springs installed in the sliding groove on the operating platform push the slider, which slides within the groove. This causes the second clamping plate on the upper side of the slider to push the sensor to be packaged against the first clamping plate, thus fixing the sensor in place. This method is suitable for packaging sensors of different sizes, offering convenient operation and good clamping effect, increasing clamping efficiency. An elliptical wheel and positioning groove are installed at one end of the sliding groove. In conjunction with the positioning post on the slider, the positioning post, under the action of the spring pushing the slider, adheres to the outer wall of the elliptical wheel. Rotating the operating knob causes the elliptical wheel to rotate synchronously. When the positioning post and the minor axis of the elliptical wheel are aligned, the spring pushes the slider, bringing the second clamping plate closer to the first clamping plate until the sensor on the operating platform is clamped, at which point the slider stops sliding. When the elliptical wheel is rotated so that its major axis is aligned with the positioning post, the positioning post engages in the positioning groove of the major axis of the elliptical wheel. The elliptical wheel pushes the positioning post, causing the slider to compress the spring. At this point, the second clamping plate moves away from the first clamping plate, releasing the clamp on the sensor. This method is convenient to operate. Attached Figure Description

[0014] To better understand the purpose, structure, and function of this utility model, a sensor packaging device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0015] like Figure 1-4 As shown, this utility model discloses a sensor packaging device, including a base 1; a vibration chamber 2 is disposed on the base 1; a motor 3 is disposed inside the base 1; a rotating shaft 4 extends into the vibration chamber 2 along the output axis of the motor 3; a ball bearing 5 is obliquely disposed on the outer side of the rotating shaft 4; a swing wheel 6 is fixedly disposed on the outer side of the ball bearing 5; a swing fork 7 is rotatably disposed on one side of the vibration chamber 2; the swing fork 7 extends to both sides of the swing wheel 6 and is rotatably connected to the swing wheel 6; an operating platform 8 is fixedly disposed on the upper side of the vibration chamber 2; and an operating platform 8 is provided on the operating platform 8. The platform has a slide groove 9; a slider 10 is slidably disposed in the slide groove 9; a first clamping plate 11 is fixedly disposed at one end of the operating platform 8; multiple springs 12 are disposed between the side of the slider 10 away from the first clamping plate 11 and the operating platform 8; a second clamping plate 13 is disposed on the upper side of the slider 10 relative to the first clamping plate 11; a support frame 14 is disposed on one side of the base 1; an injection pipe 15 is disposed on the upper side of the support frame 14 and downwardly disposed on the upper side of the operating platform 8; an injection nozzle 16 is disposed between the injection pipe 15 and the first clamping plate 11 and the second clamping plate 13.

[0016] Combination Figure 1-4As shown, the sensor to be packaged is placed on the operating platform 8. Sealant is injected into the sensor through the injection pipe 15 and injection nozzle 16. At this time, the motor 3 is started, driving the rotating shaft 4 to rotate. Simultaneously, the rotating shaft 4 rotates the inner ring of the ball bearing 5. Since the ball bearing 5 is tilted on the rotating shaft 4, the rotation of the inner ring causes the outer ring to move up and down, simultaneously causing the swing wheel 6 to swing up and down, generating vibration. The swing wheel 6, while swinging up and down, causes the swing fork 7 to twist alternately up and down on both sides, rotating within the vibration chamber 2, increasing the vibration effect. The vibration force is transmitted to the sensor through the operating platform 8. The vibration accelerates the rise of air bubbles in the uncured sealant, causing tiny bubbles to coalesce into larger bubbles, making them easier to expel. Stable vibration also reduces the viscosity of the sealant material, aiding in the expulsion of air bubbles, increasing the density of the sealant, enhancing the protective effect on the sensor after curing, and extending the sensor's lifespan.

[0017] When the sensor to be packaged is fixedly clamped on the operating platform 8, the second clamping plate 13 is pulled to drive the slider 10 to slide in the slide groove 9, placing the sensor to be packaged between the first clamping plate 11 and the second clamping plate 13 on the upper side of the operating platform 8. The multiple springs 12 set in the slide groove 9 on the operating platform 8 push the slider 10 that slides in the slide groove 9, so that the second clamping plate 13 set on the upper side of the slider 10 pushes the sensor to be packaged to adhere to the first clamping plate 11, thus fixing the sensor. This method is suitable for packaging sensors of different sizes, is convenient to operate, has a good clamping effect, and increases clamping efficiency.

[0018] An elliptical wheel 17 is rotatably mounted on one end of the slide groove 9 on the operating platform 8. An operating knob 18 extends upward from the elliptical wheel 17 onto the operating platform 8. Positioning grooves 19 are provided at the four vertices of the elliptical wheel 17. A positioning post 20 extends from the slider 10 towards the positioning groove 19. With the elliptical wheel 17 and positioning groove 19 at one end of the slide groove 9, and in conjunction with the positioning post 20 on the slider 10, the positioning post 20, under the action of the spring 12 pushing the slider 10, adheres to the outer wall of the elliptical wheel 17. When clamping the sensor to be packaged, rotating the operating knob 18 drives the elliptical wheel 17 to rotate synchronously, so that the positioning post 20 and the elliptical wheel 17 are aligned. With the short axes of wheels 17 positioned opposite each other, spring 12 pushes slider 10 to bring the second clamping plate 13 closer to the first clamping plate 11 until the sensor on the operating platform 8 is clamped. After the slider 10 stops sliding, the sensor encapsulation is completed. When the clamping is released, the elliptical wheel 17 is rotated so that its long axis is opposite to the positioning post 20. The positioning post 20 is then engaged in the positioning groove 19 of the long axis of the elliptical wheel 17. During the rotation, the elliptical wheel 17 pushes the positioning post 20 to compress the spring 12 of slider 10. At this time, the second clamping plate 13 moves away from the first clamping plate 11, releasing the clamping of the sensor. This makes the operation process convenient and greatly improves the sensor clamping effect and ease of use.

[0019] Buffer pads 21 are provided between the four corners of the operating platform 8 and the vibration chamber 2. During the process of the vibration chamber 2 and the operating platform 8 vibrating the sensor to be packaged by the rotation of the rotating shaft 4 driven by the motor 3, the vibration effect is controlled by adjusting the output power of the motor 3. Under the effect of the air bubbles in the vibration sealant rising and being discharged, the sensor itself is not damaged by vibration, which prevents it from affecting the subsequent use of the sensor. At the same time, the buffer pads 21 provided between the four corners of the operating platform 8 and the vibration chamber 2 buffer the vibration intensity at the edges of the operating platform 8 and the vibration chamber 2, preventing the connection between the operating platform 8 and the vibration chamber 2 from becoming loose and the vibration effect from amplifying.
